Yield: 72%
Reaction Conditions:
with tert.-butylnitrite;N-hydroxyphthalimide in acetonitrile at 90; for 36 h;Schlenk technique;
Steps:
23 synthesis of 2,3-dihydro-1,4-naphthoquinone
To the 25 mL Schlenk reaction tube was added NHPI 1.0 equiv., Vacuum dried for 15 min, oxygen balloon was added, followed by addition of acetonitrile lmL, t-butyl nitrite 2.0 equivalents, 1,2,3,4-tetrahydronaphthalene 0.5mmol, in the reaction tube with poly tetrafluoro plug after the oil into the pot, 90 ° C reaction 36h. After completion of the reaction, the solvent acetonitrile was concentrated under reduced pressure, and the eluent was petroleum ether / ethyl acetate (ν: 10: 1) to give 2,3-dihydro-1,4-naphthoquinone The The product yield was 72%, gray solid
